TRUE/FALSE and explain An estimate, also known as a sample statistic, is simply a rule or formula or method that tells us how to estimate the population parameter of interest from the information provided by the sample at hand.

Answer #1

TRUE.

Sample statistics is used to estimate a population parameter from the given range of values. Hence it is true that an estimate, also known as a sample statistic, is simply a rule or formula or method that tells us how to estimate the population parameter of interest from the information provided by sample at hand. It uses a certain formulas or rules or some methods for sampling procedure. Using those rules or methods of formulas estimate parameter from the population is calculated, which is unbiased, from the information provided by samples at hand.

Unfortunately, a sample (even a representative sample) is very unlikely to yield a statistic that is exactly the same as the corresponding parameter. For this reason, a confidence interval can be constructed by adding and subtracting an amount (known as the standard error) to a sample statistic (known as the point estimate). With the results, a confidence interval provides a range of plausible values for the true parameter. True False

A random sample of 50 students has a mean GPA of 2.55. It is known that the population standard deviation for the GPA of all students is 1.1. Use this information to complete the following: a) Does the information above provide an estimate of a population mean or a population proportion? b) Provide a point estimate for the population mean GPA of all students. c) Construct and interpret a 95% confidence interval for the parameter you selected in part (a)....
